Default Buck Plans

This seems unlikely, but is there a source for buck plans that I'm unaware of?

I was reading a metalwork book recently (I can't remember which one, but can figure that out if it's important to anyone) and in one of the chapters on a home built Cobra Daytona there was a statement that said the owner built the buck from plans he purchased. Wow, really?

I know I saw a place in the UK that specialized in scanning original cars and then developing bucks from that. But that seems like an expensive one-off process. It would be kind of cool if there was a place that had ready-made buck plans.

I guess really it's about "who has accurate 3D models of cars" because given that it's not difficult to build buck stations. In Solidworks you can set up a series of cross-section views several different ways. I did that for a couple of motorcycle gas tanks I built. There used to be an app called "123D Make" that could take a solid model and generate stations. (interestingly, part of it's appeal was it could also generate layers that your could cut out and stack up to make a part by blending the layers after stacking them). There is an add in to Fusion360 that does them same thing as this.



So, has anyone else gone down this path? I've been thinking a lot about building a hot rod body from scratch. It would be neat to short cut the process of tracking down an original body to build a buck from.

I know there are some models on GrabCad (although most of the styles I'm interested in aren't well enough developed to actually be helpful for this -- they are kind of flat and don't really resemble the original car to begin with). But maybe that would be good enough for en experiment.

If you were reading one of Bill Longyard's books. Bill did a chapter in his book on my build. The Plans were tracings you cut out and taped together for half of the station of the buck then flipped over for the other half. The buck stations took a fair amount of work to get things to aline and flow. In the end I don't know how close the buck is to any of the original 6 cars. They were all different. Mine ended up as my view of how it should have looked.

Thanks Mark - that's the one. Where did you source the drawings? Do they have other vehicles or was that a one-off thing?

I hear what you're saying - I wouldn't expect that you could get something perfect right from the start with this approach without a huge investment in R&D on the original model.

My thinking is that it would be a good way to get the size/scale and general proportions as a starting point to further develop the buck. Just that would be useful.

Kent White has a set of plans for a cobra buck. It is not on his web site. Call and ask for them.

I will see if I can find a link for you. It is the only buck plans he has. He got access to an original that Kent was restoring years ago. Do a search for Chuck Lindquist cobra.

Thanks - although I'm not specifically looking for a cobra buck (this week - I've certainly wanted to build one many times!). This was more a general question, like "is there a cool-car-buck-plans.com site I was somehow unaware of?

And if not, why not?
